Specification of Letters Patent.

Patented Apr. a, 1918.

Application filed July 18, 1916. Serial No. 109,920.

To all whom it may concern:

Be it known that 1, ANDREW FoLLwnILnR, a citizen of the United States, residing at Henryville, in the county of Monroe and State of Pennsylvania, have invented certain new and useful Improvements in Ventilators, of which the following is a specification.

This invention relates to ventilators and more particularly to a ventilating device which is particularly adapted to be employed in connection with railway cars.

The primary object of the device is to provide a ventilator that will create suction within the car whereby the foul air and dust will be withdrawn from the interior of the car and ejected therefrom.

A further object of the invention contemplates the provision of a pair of oppositely disposed members which are mounted on the exterior of the car and adapted to receive the air as it rushes along the side of the car whereby a suction of considerable force will be obtained within the car for effectively withdrawing the foul air therefrom.

A further object of this invention is the provision of a ventilator which consists of comparatively few parts and is simple in construction, but durable and well adapted to withstand the rough usage to which devices of this character are ordinarily subjected.

For a full description of the invention and the advantages and merits thereof, reference is to be had to the following description and the accompanying drawings, wherein is illustrated the preferred form of my invention, in which;

Figure 1 is a fragmentary vertical section through the upper portion of a car showing the ventilator applied thereto.

Fig. 2 is a section on the line 2-2 of Fig. 1.

Fig. 3 is a section on the line 3-3 of Fig. 2.

Fig. Fig. 2.

As shown by Fig. 1 of the drawing the ventilator is arranged near the top or roof A of the car and the air conveying pipes extend through the side walls B thereof and carry the suction creating devices which are disposed on the exterior of the car. Directly below the center of the roof A, on the interior of the car, is an intake funnel 1 which is provided with the funnel-shaped mouth 2 and the spherical body portion 3 the top of which is in engagement with the 4 is a section on the line 14: of

roof A. Oppositely disposed screw threaded and are adapted to support the suction creating devices, designated in their entirety by the numeral 6.

One of the suction creating devices 6 is arranged on each side of the car and each device consists of a cylindrical drum 7 which is reduced in diameter at one end and provides the tubular neck 8.' Integrally formed with the drum 7, at opposite sides thereof, are the funnels 9 which communicate with the interior of the drum 7 and are disposed in a position to extend longitudinally of the car whereby one of the funnels will receive the air as it rushes by while the car is in motion. Two funnels are provided in order that the air may be received, regardless of the direction in which the car is traveling.

The top end wall 10 of the drum is provided with a central screw threaded opening which receives one end of the air ejecting ipe 11, the opposite end of which terminates slightly above the opening in the end of the neck 8. The screw threaded end of the pipe 11 is extended slightly beyond the upper end of the drum whereby it may be received in the end of the elbow 5. The suction devices are thereby supported without the use of fastening elements.

In order that the air, as it passes into the drum, through one of the funnels 9, may be directed downwardly through the neck 8, I provide a pair of partitions 12 as clearly shown in Figs. 2 and 4 of the drawing. These partitions 12 are disposed vertically and extended for the full length of the pipe 11 and transversely across the drum 7 and neck 8. The air is thereby directed downwardly through the drum and neck and creates a powerful suction which draws the air through the pipe 11 thereby creating a suction within the car which will be maintained as long as the car is in motion.

From the foregoing it will be observed that a very simple and durable ventilator has been provided, the details of which embody the preferred form. I desire it to be understood however, that slight changes in the minor details of construction may be made without departing from the spirit of the invention of the'scope of the claim hereunto appended. V

I claim:

A car ventilator comprising a cylindrical drum mounted at the side of the car and disposed in verticalposition and including a lower"'portion"of'a" diameter less than the diameter of the upper portion,thelatter having oppositely projecting funnels communicatingawith'theinterior ofthe drumy partitions arranged" within thedrumand laterally spaced apart and terminating in spaced relation to the end-of the said lower portion of the drulm fonforming: a plurality 'the'top of the said drum and having its lower end terminating flush with the lower endof the "said partition. I

In testimony whereof I aifix my signature in presence of two Witnesses.
